气候变化对栾川工农业生产的影响

The Impact of Climatic variation on Production of Industry and Agriculture in Luanchuan

20世纪90年代以来,栾川县降水持续偏少,蒸发量增大,湿度减小,干旱发生的频率明显增多,强度加强。干旱导致的水资源紧缺,严重影响工业生产,造成粮食减产、农业生产成本加大、森林病虫害蔓延和森林火灾频发。加大植树造林、退耕还林的力度,调整农业产业结构,实施人工增雨,开发空中水资源,是应对气候变化的有效措施。

Since 1990, Luanchuan assumes continuous less precipitation, the quantity of evaporation increases, the humidity decreases, the frequency of drought increases obviously, and the intensity strengthens. The lack of water resource caused by the drought affects the industrial production severely, and leads to the reduction of food supplies ,the increase of the cost of agricultural production ,the extension of forest plant diseases and insect pests and the frequent forest fire. Therefore, strengthen the land to forests and returning land for farming to forestry, regulate the structure of agricultural industry, implement the artificial rain enhancement are effective measures to cope with climatic variation.
